I have a King James Bible, and it says that God destroyed the city of Sodom because the Homosexuals tried to molest the Angels.
Either way, I don't think the gays knew the angels were angels. In fact, the Bible text during the interactions between the angels and the gays, refers to the angels in the Amplified version as "the men (angels)" (Genesis 19 verses 10 and 12). Plus, before that in verse 9 the gay men shout at Lot: But they said, “Get out of the way!” And they said, “This man (Lot) came [as an outsider] to live here temporarily, and now he is acting like a judge. Now we will treat you worse than your visitors!” So they rushed forward and pressed violently against [c]Lot and came close to breaking down the door [of his house]. If what they planned to do to Lot was worse than what they wanted to do to Lot's guests, this to me suggests that their intention wasn't to rape his guests (the angels) -- if what they wanted to do to Lot was even worse.
This is just supposition from me, but when I put all that together it seems to me that the gay men of Sodom thought Lot's guests were men, not angels, and that they wanted Lot to get of the way so they could ask the men to join them in their orgy, not rape them. That tells me that the story about Sodom and Gomorrah isn't just that God gets mad at rape (like I've heard some LGBTQWERTY "Christians" say), or that God was just protecting His angels. God hates even consensual homosexuality more than Ole Miss coach Lane Kiffin hates punting.
You have to be some kind of stupid to buy that.
It's an indicator of how far they were gone.
Sodom and Gomorrah were already on the list to receive their judgment. Read the chapter before Sodom's destruction - the end of Chapter 18. Abraham's trying to negotiate with God for Sodom and Gomorrah, and God basically says 'sure, IF there are ten righteous people in Sodom I'll bypass their judgment'.
The Angels went into Sodom to rescue Lot (Abraham's nephew, and perhaps the only righteous man in Sodom) and his family. The Sodomites who tried to rape the Angels were just living out their depravity. They were already condemned, and 'dead men walking' prior to their attempted rape.
